Montserrat is a great host. She helped us with an early check in as our flight came in earlier than the usual check in time. She was at the apartment to check us in and shared a lot of useful information about the places to visit and restaurants to explore. She was always very responsive during our stay. She also helped us in arranging an airport taxi when she got to know that our flight was very early in the morning.
The apartment is very near Sagrada Familia but still at a quieter area from which you can easily walk to the metro station. There are some good restaurants near by to explore offering various cuisines including vegetarian options.
