We had a great stay at this place. The location was central for everything we wanted to visit. Only place we had to take the metro to was the airport, not for any tourist places. The stairs to the 5th floor are to be avoided to do multiple times a day but are definitely fine and doable. Would not recommend the stay for tall to very tall people as it's an attic but this wasn't an issue for us (1m80).
Would recommend!
