This was a great place to stay in Lisbon. The location was the main reason we chose it and it worked out perfectly. Several options for public transit are nearby to get you anywhere in the city. The kitchen and bathroom are both small but fully functional for our needs and we were kindly provided with a travel cot for our youngest child.
Note though that Jorge isn't joking about the stairs up to the top floor apartment- it can be a lot, especially at the end of a long day of walking! The last flight is especially steep and tight. Fortunately Jorge helped up bring our luggage in when we arrived.
There are three double beds, but be aware that one of the bedrooms only has a curtain for a door, so not ideal for those who go to bed before the others in the group and need quiet. We didn't use that room, so it wasn't an issue for us, just something to be aware of.
We had one issue with noisy downstairs neighbors but Jorge was able to contact them and we had no further problems after that.
All in all, a great place to stay in Lisbon!
