LOVE this apartment! The tall ceilings and natural light make it feel bright and spacious. Everything is modern and comfortable and the kitchen is very well equipped. (spices, oil, lots of plates/cups/utensils)
The only thing of note is the hot water tank is quite small. We found out the hard way...I left my husband with a cold shower after our long journey to Portugal. Not a huge deal of you plan ahead a little bit.
The building was nice and quiet during our 7 day stay and the location is perfect to explore Porto. It's not right in the touristy areas so it's very quiet and peaceful and has a local feel. We walked everywhere with our infant son, so it was still very close to everything we wanted. Highly recommend!
