Stayed here for two months and it was a great place to stay in the Principe Real area, which is close to nice restaurants, the Lisbon Botanical Garden, parks/miradoura, etc. There is no parking, but Uber is so cheap.
The apartment was clean and well maintained. The bathroom and kitchen were more than adequate with proper utisels for cooking and cleaning. The bedroom was very small where you can only get in on one side, so someone would have to climb over another. The communications with Samuel were quick and helpful. If I had questions/issues, he would reply in a few minutes. Checking in was a breeze.
The apartment is on a busy thru fare to Sao Bento at the bottom of the street, so it can qet quite noisy at night if windows are left open. No problem with noise if windows are shut. Would definitely stay here again when in Lisbon for a few months.
