The host welcomed us very well, we didn't really scheduled anything for Porto, and they explained all the things to do.
The location is super well located, close to everything, very close to the street bar, no need to use metro or else (except if you want to go to the beach).
As we stayed 2 weeks; we didn't want to go to the restaurant everyday, and so this appartment was perfect as there were everything to cook. (microwaves, oven, utensile etc...)
There is also a living room with TV, which is usefull when you want to chill out.

The only problem is the noise from the renovation just below the flat and also during the weekend, as people partying very late until 5am.
It is not so well insulated "soundproof".
Unless you party during weekend and wake up very early, you will have lot of issues to sleep.
