My partner and I stayed here for a month and we had a wonderful stay. Mike and Alice were always quick to respond whenever we had any issues. We had a couple of complications with electricity in certain areas of the apartment not working but they were able to get it fixed within a couple of days. The internet speeds were good enough for two people to work comfortably on.
The neighbourhood has all the amenities you need close by including restaurants, pharmacies, and grocery stores. There is a subway station within a 10 minute walk as well as a bus stop in front of the door. Noise does carry easily in the building so be mindful that as you can occasionally hear the nieghbours having loud conversations and the rumble of traffic outside. The building does not have an elevator and is situated on a hill so it may not be the best fit for anyone with mobility issues.
Overall I had a wonderful stay here and would definitely recommend it to anyone looking for a place to stay in Lisbon!
