We needed a place to crash with our 2 year old for 1 night, since we unexectedly wanted to add one day onto our Porto trip. João was very quick to respond to our request. The apartment couldn't have been in a better location and was very nicely appointed and we found free parking on the street. The building is old so if you have trouble with stairs/lose stairs ask Joao about that. Also he buys internet for several units per GB so when we got there at 10pm the tenant below had used all of it up. João was able to help that night to get internet.
