Stayed here for a month. In terms of location, you honestly cannot find a better place in Lisbon. It is right in the middle. I checked with host about internet before booking. But unfortunately had issues when I moved in (wifi only in kitchen and not usable anywhere in the bedroom or living room), but hosts were fast to reply and fixed it after a week. There was a bit of sewage smell coming from bathroom in the beginning. But most of it slowly disappeared with time too. The windows are high and helps with air circulation. But I wish the natural lighting in apartment was better. It’s difficult to see if it’s sunny or not outside.
Apartment is well equipped with literally everything you need and it’s quiet. Hosts were fast to respond to queries and communicates well. This property is a great choice for a short stays and exploring Lisbon.
