We've stayed at Sal Studios for 3 nights. Filipe was there when we arrived and gave us a nice welcome drink. He told us all about Porto, where to go for dinner or to see things and gave us a map. Our room (app. no. 5) was in the top of the house (a few stairs) and was very modern and clean. All rooms have been renovated recently. There is a bed, a little kitchen and a bathroom. Everything you need for a citytrip. The bathroom and bed (1m40 wide) are maybe a little bit too small for us (we are both very tall people from the Netherlands). Filipe was also accessible via Whatsapp for questions. He answered very quick. The location is really PERFECT! The appartment is at walking distance from Sao Bento (central station), Clérigos Tower (it's literally around the corner), the bar street and a lot of restaurants. We enjoyed our stay very much and would recommend this place to others!
