My girlfriend and I were very pleased with this apartment. Location is quite central in Baixo (old town/where all the action is) Porto, 10 minutes walking from the metro station. If you have luggage you can take an Uber for about 3 euro. Basically, you walk out of the apartment and in a block you have restaurants, bars and cafes, so if you want to be central, hard to get better.
The bed is very conformable, and I am a bed connoisseur, so it is the real deal, not a double-bed shoved into one. Blackout curtains so we slept great, except for some noisy neighbors one out of five nights.
The amenities are wonderful, wine and fruit and some sweets, very nice.
Finally the hosts Amelia and Josefa are very thoughtful and kind, they took the time to meet us in person, and gave us lots of local tips.
The value is solid, if you go cheaper the quality will drop for sure.
Kitchen has it all, we cooked three of fives nights and made breakfast and coffee every morning.
