A great appartment in the middle of the city centre. The location is perfect, it really can't get better. There are many good bars and restaurants next to the front door, 2 supermarkets in the neighborhood, and enough shops to visit during your stay. The appartment is fitted with all your necessary appliances. The only downside to the appartment is the collapsible couch that transforms into a 2 person bed, which must be changed every morning/evening because of space issues. Something to consider is that you need to go up 4 stairs, so this is not the right place for elderly people or w/ disabilities. Other than that it is perfect!
The host Carlos is great. He gave us tips about what to see during the day and where to eat during the night. He responds fast to questions and he is always available by phone if you need anything.
All in all we had a fantastic stay and would stay here again when we return to Madrid.
