Great experience overall - Enrique met us to check in, provided LOTS of options for things to do and responded within minutes every time we had a question. Very very professional operation.
The place is great and very livable. The soundproofing is excellent! I was amazed by how completely the sound was blocked. The outdoor space was full of white flowers and shaded by an orange tree. It's not a place to eat dinner al fresco or anything but nice for the proverbial cup of coffee/glass of wine. You can get Netflix on the TV which was actually a great bonus.
You aren't very close to a subway station -- Rato is about a ten minute walk away, and it's up the hill -- but truly Uber is so ubiquitous and reasonable that it doesn't matter very much. The immediate neighborhood has three restaurants, a grocery store, and a pharmacy within a 1 minute walk.
Some of the main tourist sites like the Alfama are not what I would consider walking distance (though I am fairly old), but the property gives you a sense of more typical Lisbon neighborhood life.
Highly recommended, and would happily stay there again!
