The flat is really nice, very clean and has everything one needs. It is very big, only the bathroom is small, but thats still ok.
The location is also great, there are two metro stations near by and a bus direct in front of the door. But I would recommend to walk doen to the river, because you will pass a lot of exciting view spots, restaurants etc. Also the famous tram 28 drives through the street. But as the bedroom is located in the back, it is very quiet and you will get some peaceful sleep.
Sonia was extremely helpful and kind. She did not only help us before our stay but also during our stay. She answered all our questions quickly and also gave us same great tips.
I would definitely recommend to stay here when in Lisbon and I would also love to come back again.
