We just stayed at Rosa's apartment for 9 nights. It was a wonderful stay in the best location. It was a 5-7 minute walk to Plaza Mayor and Puerto Del Sol. Rosa was very attentive and made sure we had everything we needed. Her place may look small, but my husband and I had four bags with us and still felt like we had enough room in there.
It was so nice to have a place that felt like home after a long day out walking the beautiful streets. Tirso de Molina (Metro) is very close and i recommend using it, we were a little hesitant to use the public transportation but it was wonderful.
While my husband and I didn't go out to enjoy the night life, there was a large amount of night life close to the flat.
My only complaint is the noise. The complex is rather noisy and often times are to sleep. The flat gets really stuffy so you want to have the window open, but it gets noisy.
One highlight to mention is the bathroom-- It was VERY VERY nice.
All in all we loved our stay with Rosa.
