We stayed at this studio last weekend and it was great. The location is great and very easy to find. It's small and cozy, we love it! Rita provided us with a very clear instructions on how to get to the studio from the airport. We really appreciate it. It's only a slight inclination so don't worry if you have big bags.
Communication is super awesome with Rita. She reply very fast and check in was easy. Even during our stay she helped us with more information.
Studio is clean, bright and tastefully decorated. The bed is comfortable, very good after a tiring day walking around Lisbon. There's a home made guidebook which is super awesome. We did the self guide walking tour for Alfama!
Kitchen and bathroom are small but for us it was substantial and good enough. Street is quite, Internet connection is great. Water pressure is good, there's also hot water that stays hot. We didn't watch too much TV but the have cable TV so we were able to watch some English news and programs.
Overall we enjoyed our stay very much and recommend this place to everyone. (Although it can sleep 4 I think it's nicer and more enjoyable if you only have 2 person staying)
