We had 2 adjoining rooms for £66 and the facilities for that price were ok but I would not rate it a 4 star hotel. The beds were comfortable but there was only a sheet on them. We found some duvets in the cupboard but there were no covers on them and during our 4 day stay no covers were ever put on when the room was cleaned which i thought strange. We had a room at the front of the hotel and it was very noisy from the traffic below. You pay extra for wifi and there was no key for the safe so presumably you pay extra for this too. We did not pay for breakfast so can't comment on the quality of that. Staff were helpful, and most spoke some english,but the older staff were not friendly or welcoming and were sometimes rude, finishing their conversations whilst you waited to speak to them. They will hold your bags for you once you check out if you have a late flight which was useful.
In terms of location, there is a Lidl shop opposite for supplies and a lovely bakery a few doors down for breakfast pastries. There is a great park behind to stroll around and lots of bars in the immediate area.
The taxi fare from the airport to hotel Praga was 38 euros. 30 euros plus 5.50 airport supplement and 3 euros Sunday evening supplement. The tube to the airport takes an hour and cost 5 euros each, 2 euros for the fare plus 3 euro supplement. Most tube journeys cost between 1 and 2 euros or you can buy a 10 trip card for 12.20 euros.( you can use this to get to the airport and just buy a 3 euro supplement card) There is also a bus that stops right outside hotel to the plaza mayor but we didn't take this preferring to walk.
We did a day trip to Toledo which I would highly recommend. From the hotel walk 10 mins to plaza Eliptica and get the ALSA coach service to Toledo (directo). Cost 9 euros return and took 45 mins ( not 1.5 hours as the tourist info told us). The service runs every half hour from 6.30 am to 10 pm. The bus drops you just outside the city walls so you can walk up to the centre. It is lovely to walk around and there is a stunning cathedral to see - cost 11 euros to get in and go up the bell tower ( children aged 12 and under are free). To get the train would take 30 mins on underground to station then half an hour on train then a bus journey and costs 24 euros return.
Other money saving tips would include visit the museums in the evening as they are free during the week. Museo del Prado is free from 6-8 pm and Centro de Arte Reina Sofia from 7-9 pm. The palace is free to EU residents (show passport) on Wednesday 3-6 pm and there is a changing of the guard ceremony at the palace from 11-2pm each Wednesday ( we saw it at 11.30).
Madrid is a great city with lots to see and do and hotel praga is a good base, although a little way out from the centre, but if you are not on a budget I would look elsewhere.
