our stay in Sergio appartment was perfect ! Very clean, we were able to leave our luggages before checkin in the morning which made our stay in Lisbon just perfect ! The street is very nice and all restaurants around are excellent, the tramway is right behind the appartment street.
The street is a bit noisy during the day but it makes it alives and make us share locals life. Very very quiet street during the night.
We stayed only one night but it was we stayed one week !
