Location, location, location! Before this three week long trip to Barcelona, I had visited the city on two previous occasions for 2-3 nights each time, so I felt like this apartment was in a pretty good location...in fact, the location is excellent! I can't imagine a better spot in the city, less than a block from Gran Via and the Urgell metro stop, in a great neighborhood, and walking distance to all the best spots in Barcelona. Plus, the area is quiet at night since there are no bars or clubs too close by. We travelled with our 9-month old and they had a portable crib all set up for him. He is used to sleeping in his own room, so we put him in the bigger front room, while we slept in the smaller room (because it's completely interior it has two small windows that open into the living room). This way we could hang out in the living room at night without worrying about waking him up--this worked really well for us, and after adjusting to the time difference we all slept great!
Noemi was super communicative and friendly and responded quickly to my messages, making us feel incredibly welcomed and like we had someone we could rely on while we were visiting Barcelona.
Little things that I ended up really appreciating were having a Nespresso machine like we do at home, the amazing pizza place and great Colombian food just downstairs, and having a landline to make local calls (since I wasn't able to from my U.S. cell phone). I would highly recommend this place to any couple or small family travelling to Barcelona.
