I stayed here for a week for a conference at the University of Lisbon and it was lovely. The apartment is cheerful and bright with big windows. Although it is on the "ground floor," It is a level above the street so there is a fair amount of privacy when the curtains are open. The heavy room darkening curtains helped me sleep well in the comfortable bed. Despite what other reviews have said, there was no noise from either neighbors or construction. It was very quiet and safe. The apartment is spacious (about 700 sq feet) with a large bathroom. It is well equipped: washer/dryer, dishwasher, central air (very rare in Europe), a Nespresso machine, a toaster, pretty much everything you need. It is a short walk (5 minutes) to the Metro and numerous buses, and centrally located in the sense that the major art museum is about a 15-minute walk in one direction, a great gym (Portuguese Gym Club, 15 E for a day membership and they have everything and are very friendly) is nearby, and you can walk to the historic areas near the waterfront in about 20 minutes (or take the metro and be a block from the waterfront in 10 minutes). The University was easy to get to as well, just a short ride on the metro and a 10-minute walk. The huge park (Eduardo VII Park), a 2-minute walk from the apartment, is beautiful and has an amazing overlook to the sea. Communication with the host was good and I was allowed an early check-in, very nice given that I got in at 8 am after a long flight. I would gladly stay here again.
