We travelled as a couple to Madrid in March for 4 nights and had a great time staying in Lina's apartment which looked exactly like it does in the photos. The space is perfect for 2 or 3 people with a double bed in one bedroom and a couch in the living room and all amenities necessary for the stay. The apartment is located in an extremely convenient area, very easy access from the airport and all major tourist sites. Most sites are within a short walking distance that we really didn't even need to use the subway (station is right across the apartment), and it's very easy to catch a cab if need be right in front of the building. There is also a grocery store right next door which was an added convenience!
Lina was also an amazing host communicating with us often and checking in to make sure we were having no issues. If you are looking to explore Madrid, we can't recommend this apartment enough for its convenience and great host!
