We loved our stay at this place. It's very charming with an UNBELIEVABLE view of the city. We were there 10 days and by the end we felt like we truly lived in Lisbon!
Joana is very responsive to any inquiry. She replied within a few hours every time I sent a question, so I felt confident when we arrived in Portugal from the US everything would be as promised. And it was.
All of the appliances in the kitchen are very modern. One night we stayed in and cooked dinner from food we shopped at local markets.
It's a loft style space, so very airy. We were there in October, so the temperature outside was comfortable. I can't comment on the a/c as we never turned it on.
It's the top floor of the building so be prepared to climb stairs to get there. (We figured there are SO many hills and stairs in Lisbon anyway, what's a few more?)
It's a 2 floor loft with the bedroom on the top floor. The ceilings are slopped, so if you are tall beware of your head walking around the sides of the bed and in the master bathroom. (I'm 5'1", so I didn't have a problem. My husband is 5'9" and he was okay too.)
It's also in a neighborhood known for bars and late night partying on the weekends. The street is tucked back off the main party strip so it's not too loud, but you might hear some sounds drifting in, especially if you open the window for airflow. It didn't bother us, but if you are a sensitive sleeper, bring ear plugs.
Also, like so many streets in Lisbon, its narrow, so some taxis might not want to drive all the way down. The apartment is only a few buildings from the corner, but you may need to wheel your luggage from the corner to the building itself.
Oh! And if you are traveling from the US remember to bring/buy a European adaptor for your electronics or you won't be able to plug in to charge your phone.
We'd definitely stay here again.
