My son & I stayd for 7 nights in July 2019 and had a great tine. The location of the place is very central, easy to get to all the sights as well as to the subway and train station. It's a very lively street with the famous Bica train right outside. At night it gets quite noisy, not from the tram, which stops at night, but from people enjoying themselves. Once we closed the windows, tge nouse was gone. There's a little balcony facing the backyard with a little table, enough for 2 to sit and enjoy a quiet glas of whine. No noise there. Kitchen and bathroom are fully sufficient and clean.
The photos in the ad show exactly what the place looks like. Both hosts Carlos & Joao are very attentive and responsive. Apparently we were the 1st guests to stay in this aptmt, that's why we could not find any reviews. No regrets, anyway. They also picked us from the airport and sent us back (at 4am) for 25 Euro each way. Any of our questions during the stay were answered promptly + fully by whatsapp. Also both of them are full of local tips if you are interested. We followed the suggestion to visit Sintra, a mountain town less than an hour away by train with beautiful hiking trails + castles to see. All in all a great place to stay if you don't mind the lively neigbourhood. For us, even though we are not party animals, it was fine.
