Unfortunately the recent reviews of this hotel proved to be absolutely on the button. The lobby area is by far and away the best part of the hotel but you can visit this for a drink and stay elsewhere.
I don't think I can really add anything new with regard the lifts or lift as it was for most of our 4 night stay. Our kids thought it was funny to begin with but it wears pretty thin very quickly. There is work going on for the other 2 lifts but it didn't appear close to finishing.
The staff tended to be pretty uninterested at best and downright rude at worst. the latter refers to the lady on reception in particular.
We did get nice notes from our room maids and the towel sculptures were great. The air con worked in only one of our 2 rooms for the first day only. After that it was sleeping with open windows, less than ideal 5 floors up with kids.
Breakfasts were ok. Bit of a struggle to get cutlery and cups. best bet was DIY.
It may get itself sorted out but at present give it a miss although it's worth a drink in the lobby

We were very optimistic when we arrived as the foyer is stunning and check inwas very smooth and quick.
However, our room (525) was small and in obvious need of a serious up date.
It wasn't very clean but we were tired so settled down for the night.
Everything you have read about the lifts is true - they are slow and unreliable but they also seem to run all night and stop on every floor where they ping seven times. it turned into some sort of bizarre torture as we lay awake counting them.
The bed side light didn't work and several springs appeared to be loose in the bed
The shower was not good and it was a battle to get the temperature right as it switched very quickly from hot to cold with a very weak stream.
Breakfast was characterised by mediocre food and lacklustre service. It took several goes to get a table, then a cup, then a saucer and finally a cup of coffee. Staff seemed to be very busy clearing tables but not doing much else.
We have been to Havana before and stayed at Telegrafo and would recommend you try and get a reservation there and give the Sevilla a miss.
It looks shabby and instead of upgrading it they just appear to have painted over everything on several occasions
We were only staying two days but

We stayed for 3 nights at the Sevilla in November this year. The room we were allocated was the size of a postage stamp - we arrived to find dirty towels laying all over the bathroom (it had clearly not been cleaned) and the damp smell pervaded everywhere. The one chair in the room was broken and the "wardrobe" (it was 2 feet wide) had the door hanging off its hinges. Overall the room was filthy - a large piece of the ceiling coving was missing and the aircon unit in the ceiling was particularly dirty. The "view" from the window was out over what looked to be a rooftop building site. There was one lift in the whole hotel working - the goods lift - which was again filthy at best - you could expect to wait at least 10 mins for it and then have to travel in an over-loaded lift with the dirty towels trolley. The service was shockingly slow - we asked to change rooms (but had to spend one night in this room initially) - it took them over half an hour on reception to get the key to the new room to us and even then they gave us the wrong key!

We wanted to stay somewhere more traditional in Havana but we would never stay here again - it needs updating at the very least.

Havana is a wonderful and interesting city, and the Hotel Sevilla is well placed to enjoy the best the city has to offer. You will be very impressed when you enter the hotel with the size and Grandier of the lobby reception and the patio bar where bands play throughout the day and evening. On the 9th floor there is a stunning restaurant with wonderful architechture and the best views over havana in the city. Breakfast can be taken there for a supplement of 5 pesos a person and is well worth it for the views on one day of your stay at least. The breakfast actualy isnt quite as good as that which is available in the standard lobby restaurant, which initself, at best is mediocre. The hotel has a rich history and the corridors are lined with photographs of more prosperous times.
Unfortunatley everything else about the hotel is hugely disapointing given the grandieur of the public rooms. The main lifts are being refurbished, so you have to use the service lifts. Knowing this was going to happen, the hotel has not bothered to redecorate the area or even cleaned the lifts which were filthy, you could hear the lifts going up an down in our room and every time they stop on a floor a bell pings 4 times day or night. The rooms are built around a open space and the sound echos throughout the floors.
Inside the rooms are drab and dreary, the furniture is quite good but the age of the decor is awful, our room had a large damp patch on the wall as you entered, there was a crack in the glass in the window that ran its whole length, paint had been splattered on the bathroom tiles some years ago and had never been cleaned off, the shower bath valve did not work, and we could only get hot water by complaining and waiting a half hour.
There are gaurds on the hotel entrance but this makes little difference as i was aproached by tour touts right under thier noses in the foyer and also by the horse drawn taxi guys while i had a coffee.
I would recommend you visit the hotel but could not at the moment recommend you stay, this is an embarasment tothe accor brand.
