Ana and Sonia (who assists) were easily accessible during our stay and check in with Sonia went smoothly. We were running late due to traffic but Sonia was very accommodating and met us in person. The apartment is beautiful, bright, and had an excellent layout with lots of space to accommodate our group of 4. The location was close to restaurants, bars, and all the places you would want to explore in Lisbon. It is in a lively area, just off a main street, but inside the apartment it was very quiet with the windows closed. The only noise we did notice came from inside the building from the stairwell. There are quite a few other AirBnb/rental units in the building and some construction taking place in the unit across the hall which made for increased foot traffic in the stairwell. We did have issues with the WIFI during our stay. Ana had Sonia make some calls to the service provider and sent a cousin to see if they could identify the problem. However, none of our devices were able to hold a reliable connection and we would be regularly disconnected and reconnected over the 4 days of our stay. Ana did make the generous offer to move us to a different apartment 300m away but we chose to stay. We also needed some additional toilet paper and there was some left at the apartment the next day which was very much appreciated. Overall, we had a very comfortable stay in Ana's apartment and great time exploring Lisbon.
