Carlos' appartment was very nice, not too big but comfortable. Very well furnished and ready to use, we found it very comfortable.
The neighbourhood is really beautiful and quiet, but rather far from the centre of Porto -- unfortunately public transport was not so good, but taxis are also not too expensive. All in all we loved the location, but we also felt the logistics were a bit complicated.
Carlos was super helpful and responsive, very quick to reply and very helpful with everything. We were very greatful for his support. Thanks again!
