Joana was one of the nicest hosts that I ever been with!!! The communication was excellent and except to be welcomed with a huge kindness!! Regarding the house: Localisation is really good! You are really close to the night life best places and all of the historic centre is located at a 5/10 min walk distance! To the river you will be at a 15/20min nice walk distance. The building/house is old but it suits well with the city, since the city itself has an old charming environment regarding the architecture of the houses. The house is clean and the places to sleep are spacious and comfy!! Maybe a problem is the fact that it has only a bathroom but obviously we already knew it and managed it well (we were 5). Just be careful because the hot water has a limit of 80L (if I'm not mistaken) for a certain period of time. So be careful not to run out of hot water. Another problem that we had was with the heater, we didn't manage to get it to work following the instrucions but maybe this was our fault! Apart from that, the house is perfect! Clean and has everything needed!
So, in a nutshell, it's a house to stay in Porto!!! Joana is so so nice, 5 stars!!! And the house is really good too!
