I cannot say enough positive things about Hotel de las Letras, we stayed for 5 nights over Christmas. The hotel was well appointed , comfortable and spacious.
We had a lovely room on the back side with a huge terrace. The location was perfect , just a short walk from the Metro , short walk to Plaza del Sol, short walk to Chueca ( see a pattern..?) .. It was central to everything! The only issue we had with our stay was the safe kept resetting itself & we had to call for service twice. I was amazed how quickly they replied to this as they had a technician at our door within 10 minutes, even on Christmas Day. Also the other thing was they only had an automatic circular door - which proved a bit tricky with a large suitcase ( at least for me)
We didn’t go to the bar/restaurant so I cannot comment on that portion. However, Madrid has thousands of places to eat & there is a Faborit, a local coffee shop, practically across the street – so it never even crossed my mind to eat or drink at the hotel.
To sum it up for a central location, nice décor, comfortable room , in a beautiful building with character, can't go wrong with this choice.
