Wow. This flat is so wonderful, it is one of the best bargains I've had on AirBnb. Location very central, yet on a quiet lane so no noise. Few minutes walk to anything--cafe, restaurants, shopping, bars, etc. Basically in the most heavily touristed part of Lisbon. The flat is a newly renovated building, and everything is modern and in great shape. As another reviewer noted, the quality of the linens are also top notch, that of 4 star hotels. It also has A/C, which is uncommon in my experience so far in most of the Iberian AirBnbs.
The hosts are incredibly helpful, friendly and responsive. They have a very detailed guide to Lisbon in the flat. Pedro, who met us, also spent quite a bit of time suggesting a range of places and activities. They also respond immediately to any queries. Ana and Pedro are amongst the very best hosts I've have dealt with, providing one of the best AirBnb pads I have experienced. I hope to return as we also adore Lisbon.
