My boyfriend and I spent two weeks in Martha's apartment and loved every minute of it. It's an extremely spacious place, perfectly equipped and very clean. We had to work remotely while we were in Lisbon and the apartment provided us with everything we needed, good Wifi, a large table and multiple rooms to have zoom calls separately if needed :)
We loved cooking in the amazing kitchen and having lunches on the beautiful sunny balcony.
The area is very nice, close to the Gulbenkian Museum and a large shopping area and had several very nice restaurants and cafes close by. The apartment is also only a short walk from the metro station Saldanha, from which everything can be accessed in no time.
Thanks for letting us stay and we'll make sure to come back next time we are in Lisbon!
