Carlos's apartment is wonderful. It is larger than I expected for a European apartment in the center of the city. There was a full kitchen and separate dining room, and a large living room. It was the perfect size for 3 people. The apartment was very clean. It was located in a wonderful part of the city-a short walk to many restaurants and shops, and La Sagrada Familia. 2 metro stops were within easy walking distance as well. Despite its central location, the apartment itself was very quiet. Carlos was very pleasant and quick to respond to texts. I will definitely stay at Carlos's apartment when I return to Barcelona.
