House was in amazing location, as Porto is small city the apartment was almost near center and we could use tram and busses easily.
House itself was clean, it has TV with Netflix which is amazing.
We were in flat just 4-5 hours because we wanted to go around city. But we had 2 problems: heating and shower.
There was just 1 heater at whole house which was not enough to heat up and house was so cold at evenings. Next day they brought another heater but to be honest it was not enough as well. So, just make sure you wear something good.
Secondly, we had problems with shower. The water was getting cold just after using shower for 5-10 mins. That happened many times.
Overall experience was good though.
