We really enjoyed our stay in this flat.
It is perfectly situated, we were able to visit everything by foot. There are supermarkets and "mercados" where you can find refine fresh foods.
There are a lot of typic and lovely restaurants in the neighborhood.
Very accessible by public transport.
Plaza Mayor is really closed too.
The flat was clean and nicely decorated. The bed is a little bit original but I found it cozy.
Yes it is a little bit noizy during the wk but we didn't really care as we like lively cities and go out in the evening too.
We recommend this flat, this is a really good spot if you want to visit Madrid and we will definitly come back to enjoy some tapas y sangria.
