This apartment is so beautiful, comfortable, well-located, well-hosted, and well-appointed, you really do want to rent it. We stayed for four weeks, long enough for any issues to rise to the surface, but any concerns were minor. Unless you are a very light sleeper because the noise from the street can be significant. We found that we walked so much every day that we slept through most of the noise and by morning it was pretty quiet until the first car honk the day. The upstairs neighbors are very quiet and you barely hear anything from them. The Internet is mostly good. There was one night that it was out for a few hours, but for the rest of our stay it never went out for more than a minute or two. The router is in the other apartment but there is a signal repeater in the unit. We loved our stay in this apartment and if we moved to Barcelona we would want to be right in this neighborhood. Being between the light rail and the metro made getting anywhere so quick and easy. It is also very convenient to the bus lines. You can also just walk anywhere – especially to two streets that have lots of outdoor dining and are very beautiful and walkable. Thank you, Adriana!
