We had an amazing stay with Noemí, and would defintly recommend the place.
The room was suitable and we had our own private bathroom. The location is 2 minuts Walk to the metro which only took about 5-7 minuts to Gran Via. If you are up for some bars and drinks, la latiner is the perfect place to be. (The appartment is located in la latiner).
There is 2 Big supermarkets next door and also some cafes and such.
Also to mention is the Big pool, that was availble for us.
Noemí is a good host, she speaks a little english, but assisted us finding some good restaurant i Madrid. She was openhearted and happy every morning and Night when we drop in and out of the appartment.
