We (3 ladies) had a wonderful time during our visit to Lisbon, and stayed very comfortably here. The apartment is very close to Bairro Alto - and really ANY of the other boroughs of Lisbon (Baixia/ Alfama/etc), as Lisbon is relatively small and very walkable. It was very easy for us to also take Uber to any further destination such as Belem/ Sintra.
The boutique apartment is very charming, with nicely done modern windows to let in the cool Lisbon evening breeze. :) The street is quiet and the neighbourhood is safe, with a grocery store very nearby for anything you need to stock the kitchen. The host also graciously had stock of some kitchen items such as sugar, salt, tea, coffee, olive oil, etc.
The host was easy to contact and quite quick to respond. We arrived in the later evening and unfortunately did not have a chance to communicate with the host upon leaving the airport, so we had to wait a bit for someone to open the door for us. This was not a big deal as the neighbourhood was safe and the host was very reassuring in her constant contact with us as we waited.
There are enough beds for 4 people - 4 twin beds. The 2 in the back bedroom had slightly stiffer mattresses, which needed a bit of extra cushioning...but that will obviously be a personal choice.
The bathroom was small but smartly layed out - with a fun LED light show surprise in the shower head! ;)
The host was very flexible with our schedule and check-in/check-out. We would definitely recommend a stay at this home while you are in Lisbon :)
