I stayed here for 1 month, and it was amazing!!
The location is prime - You're a very quick walk from the metro, as well as some great restaurants, bars and coworking spaces.
The apartment - was very clean and cozy, the bed was extremely comfortable and the wifi was strong. As I was staying for a month, I was offered fresh towels and a change of sheets weekly as well as a full apartment clean midway through my stay which I really appreciated.
Communication was amazing from the very beginning and I would definitely recommend staying here whether it's a short or long trip. One of the best spaces I found in Portugal.
