The flat is cosy and comfortable and looks accurate to the images. We were met by Miguel at the apartment who gave us a few tips, a little tour and the keys to the place (as well as a bottle of wine and some pumpkin jam, which was a lovely surprise). It was clean, the main bed we used was comfortable and the main bedroom has plenty of space to get ready in the morning and keep your suitcases. The second bed is in a foyer area as you enter the flat (which we didn't need to use) so it may not be the nicest place to share for 4 people. The patio is lovely to have breakfast on in the morning (though it doesn't get any sun) and the kitchen had everything we needed to cook from dishes to pans to oil and seasoning (and a dishwasher!). We weren't disturbed by noisy neighbours during our stay at all and the area seems safe.
It's a 4-minute walk from the nearest metro station (Anjos) and from there it takes about 10-20 minutes to get into the city centre with a few small shops, a small supermarket and a Lidl within walking distance.
Overall we had a great time!
