Great vacation get-away. We were warmly welcomed by Crisi, who showed us around the apartment. The place was extremely clean and well decorated. It has a cozy feel to it and it not cluttered with things.
The most incredible part was the balcony. We had an entire table and couch/chairs out there to enjoy coffee, breakfast, dinner, etc. The 6th floor view was beautiful and truly a highlight of our stay. You can tell they care about taking good care of this place based on the time they put in decorating the balcony with plants and with maintaining them.
The location was also excellent. You are near all of the great tapas places of La Latina (we loved Juana La Loca) and also within walking distance of many of the great sites of Madrid. This apartment had everything we needed for a few nights in Madrid.
