We stayed at Room 6 of Santana Guesthouse for 6 days in March.
We arrived much earlier than check-in time 15:00, and the room was already available and cleaned for us to get in. After a sleepless transfer night at an airport it was really nice to take a rest and not to wait for a check-in time. We are really grateful for that 😊.
During our stay, we had an opportunity to cook for ourselves at the kitchen and to store our products in a refrigerator. The kitchen is really good with everything we need.
Bathrooms are shared, so every guest should respect other guests, especially at night in order to not make too much noise (the bathroom on a second floor shares the wall with a Room 6). Also try to be quiet on the second floor corridor at the night, since the talks can be noisy :)
There is a conditioning system in a room, so we could heat or cool the air inside. It was useful for us in March.
Summarizing, I conclude that Santana Guesthouse was a decent place to stay with a perfect location, and I would consider to stop here again during our possible future Lisbon trips 👍
