I didn't meet Montserrat, but I did meet and communicate with her son Alex. He was very quick to respond to any questions prior to and during my stay in Barcelona and gave great suggestions of local restaurants in the area. The apartment is also in great location - it's about a 10-15 min walk to everything but also a 2 min walk from the metro station. The only downfall of the apartment is it doesn't have an elevator and you have to walk up 6 flights of stairs (92 steps-I counted) to get to the apartment, which is fine on a regular day but carrying your luggage up upon check-in and down upon check out can be difficult if you have a lot of luggage. If you don't mind the steps than this is a perfect place to stay and Alex was a fabulous host!
