Everything about the Inter is as good as can be expected, the service and staff are first rate and throroughly professional, the facilities are excellent, and the prices high. My only gripe is having to pay for internet usage in 2013 seems so behind the times and just pure penny pinching. We stopped being charge for tea and coffee making faciltiies in the room many years ago and surely internet can not be far behind.

We stayed for 4 nights at the Intercontinental and my partner is an Intercontinental Ambassador. We had booked a room with river view, the breakfast was included, the only draw back was that we had to pay for the internet.
The gym and pool are very nice and the staff is friendly. Our room had a good size, the river view was just breath taking and the staff didn't forget to tell us, that they had upgraded us. How, we still don't know... The room wasn't bigger than other river view rooms.
The breakfast has a big range of different items: french toast, pancakes, eggs in all variations, fresh made omeletts as the customer wishes, sausages, grilled veggies, pastries etc. It a good choice. They even offer rice and miso soup for Asian guests.
The cleanliness of our room was good, esp the first day then we didn't get any update on the weather anymore and well, you could see that they just rushed through the room.
I didn't like that the receptionist had to repeat it tow or even three times when we checked-out that they had upgraded us. Well, that's one of the advantages to be an intercontinental ambassador for what you pay with an annual fee.

If you stay here try and get a Danube view as it is the best view I have ever had in a hotel, views of the chain bridge (although we didn't upgrade our room, we joined the Ambassador programme which entitled us to the river view which is a years subscription for $200 and it entitles you to upgrades throughout the intercontinental group). To be able to sit in the window and appreciate the views was just fantastic, thats when you finally get out of the comfortable bed.

Location is great as there is a tram stop immediately outside the hotel. Depending on how long you are staying in Budapest, the travel ticket is good value. We purchased a 36 hour ticket but for about 4 euros more you could have got a 7 day ticket. Check before you buy. The tickets covered tram, metro and I think bus too. We even got on the finicular railway with this ticket.

Staff were very courteous. We stayed here over New Year so it was very busy (and my cough cough 40th birthday). We did ask the concierge where the best place for the firework display would be but he didnt think know if there was one. We found that alot of fireworks were happening impromptu outside the hotel on the tram tracks and also in the main square. Location wise though vorsmarty square was less than 5 minutes away.

Breakfast had a very good choice of food continental and international including japanese dishes, egg dishes were mostly on request.

Would definitely be back here now I am part of the Ambassador programme.

The location is perfect, service is very good and the rooms (standard ones) are also good. Breakfast buffet offers a wide variety of food but fresh juice and fruits would be welcome. The business facilities were great even for a group of 200 people.
Only minus point: the bar shuts at 1 am even on a Friday nights...
