This is a very clean and well maintained apartment perfect for a family or group of friends. The location is very central and there are lots of places to walk to for food. The supermarket across the street made it very convenient to pick up any supplies.
Our experience dealing with Eduardo was very professional and they were responsive to any questions we asked.
The location is great next to Placa Catalunya and metro station is a 1-2 minute walk (although we ended up taking taxis due to some mobility issues with elderly parents) and the street is very busy with tons of taxis going by. The apartment was on the 4th floor and we couldn't hear any noise from the street. I recommend this for your trip to Barcelona.
