The hosts were all the time very nice and supportive.
I had a problem with the bathroom door and they've sent an very nice technician fast who fixed it very smoothly.
The apartment is close to a popular viewpoint, which is also a reason why you need to go up a lot (which is pretty common in lisbon)to come to the apartment. With luggage you need to prepare for a little workout :D
Same if you go to a supermarket.
Upstairs (bedroom) is a very well working heating but downstairs is just a little electric heating. Because i was working from their all day and the house does not catch sun i was a little bit freezing. Its a good place to enjoy some days in lisbon.
