The communication was perfect and tim replied very fast. Check-in was also good. The Studio is well located, 5 minutes from the station, near the river and you can walk to the sights. Supermarket and div. shops in the street. The flat is spacious and you have everything what you need for your stay. There is a heater but the room needs a lot of time to heat up.
I recommend the studio of Tim for your stay in porto. Thank you Tim for all your information.
