My family and I really enjoyed our stay at Cesar's place!
Communication - communication with Cesar was very easy! He met us at the apartment and gave us a tour of the place. If we had questions or concerns, Cesar responded immediately.
Apartment - the apartment was spacious, clean, and had all the amenities we needed to cook our own means in Barcelona. We felt right at home! The beds were comfortable, bathroom was clean, and the water pressure in the shower was fine. Noise travels easily between apartments, so we had to be cautious of the noise we were making.

Location - fantastic location! A 5-minute walk to the Metro takes you anywhere in the city.
Overall, if my family and I found ourselves back in Barcelona, we would definitely stay here again!
