We had a vey pleasant stay at Ana's compact apartment.
There is a comfortable amount of room for 2 with a very well equipped kitchen and washing facilities. Everything is very clean and it seems like a safe surrounding neighbourhood. We were greeted with ease and the communication via Whatsapp with the host was an effective way to organise our arrival. The bed was also extremely comfortable!
I would recommend this apartment for exploring Lisbon with ease. There is a bit of a hill to climb up from the centre of town, but with a glass or two of delicious portugese wine the evening ascent is made easier!
