Mònica is a wonderful host and responded quickly to my emails! She left us with a map of Barcelona (very helpful) and walked us through the apartment. The apartment itself looks exactly like the photos - very clean and modern. The rooftops are amazing! The apartment comes with air conditioning and we had no problems with hot water (as another reviewer had previously mentioned). I love the Gràcia neighborhood - there are so many wonderful places to eat. The elevator was very helpful, although you could hear people using it throughout the night. However, after a couple of nights we got used to the sound of it.
