We spent three nights at Second House for the start of our Portugal trip. It is in a great location and the Lisbon central city is very walkable. We ended up walking everywhere instead of using the metro or trams. While located in the heart of the historic district, the apartment is relatively quiet at night. The apartment is well equipped and also has a washing machine, which is very nice if you are doing a lot of traveling.
The bath has a lovely shower with plenty of hot water. The linens are nice. Kitchen is well equipped. Good sunshine during the day. The hosts are very easy to reach and let us check in early the first day which was very nice. Overall, we highly recommend the property.
