Daniel is a great host- very responsive and helpful. He provided help with transportation from the train station and helpful recommendations of places to eat in the area, which is tricky for large groups.
This is a very active part of town, and we were there over New Year’s Eve. If you are sensitive to noise, plan to use earplugs and/or a white noise app on your phone, because it seems like a busy place all year-round.
It is really easy to get around historic Madrid from this spot. The apartment is very well-located. It is spacious, and there were enough chairs for our group of 13 to congregate in the kitchen/living room for meals.
The apartment feels worn and could use some TLC. The pictures present a fresher feeling than we found. We were comfortable there. It was easy to adjust the temperature in the unit.
The bathrooms were small, especially the 3rd one (very tiny).
All in all, a good option for larger groups.
