The apartment is in a good location and in a nice building. It looks basic, but mostly comfortable. We’ve received a message offering to pay €10 for a more convenient checkin only to find out that the place has lockboxes with the keys anyway. The major issue is the absence of an air conditioner or a fan and no screens on the widows. It was too hot and impossible to sleep even on a chilly night and when you open the balcony/windows mosquitos are flying in. The other problem with the open windows is noise from outside. Overall the sound proofing is non existent and you can hear neighbors who were coming back loudly very late at night. There’s a lack of shelving in the bathroom and at the sink, the body wash is on the floor of the shower and there’s nowhere to put anything if you need to. We decided to stay an extra night in Porto, but booked a hotel and finally got a good night sleep.
