Kristian's place is in a great location. My friends and I were able to walk everywhere and never had to pay for a cab or take the metro! Kristian was great with communication, answering texts, and giving us great tips for places to eat, drink, and visit in Madrid.
However, we are disappointed in terms of air conditioning and noise in the building. The bedroom with the twin bed did not have any air conditioning at all. Instead, there was a partially broken fan that made a loud flapping noise that made it impossible to sleep. The air conditioner in the main bedroom leaked immensely. The first night, water leaked from the air conditioner all over the floor, soaking our clothes. The second night, we used a bucket and had to listen to the sound of water dripping into the bucket all night. The second fan in the living room was completely broken and did not turn on at all.
Although Kristian's apartment is on a quiet street, the walls of the apartment are paper thin and we heard the neighbors coming home at all hours of the night.
