We like this place so much!!!
Defenetly, I will recommend to stay in Tomas Apt.
Everything was good: location, big and comfortable bad, clean, towels, dryer..
And thanks for the advices about city!
Be prepare, coz its the center of the city - its loud in the evening and sometimes in the morning. We are ok with that, so its wasn't a problem for us.
It is very good place to live in Porto!
