In general: a very small apartment in the center of Porto, suitable for 1 or maximum 2 nights disposing you to spend as minimum time inside, for short (<170cm of height) people. We stayed here 2 weeks.
Profs: centrally located you can reach any place by foot; a freshly renovated apartment with a small kitchen to make a short breakfast.
Cons:
1) Located in a top of mountain so each time you return home you have to climb up;
2) Ground floor, having a 2-meters corridor between the neibour buildings, making it a lovely and safe place for pee-everywhere-lowers, resulting in a horrible smell 24/7. We bought a pack of ACE toilet cleaner botles and emptied it out with a ton of water on the street, but finally the 30% of smell still stayed there; the owner could not do nothing with this (or didn't want?) as it takes place outside the ap;
3) There is no way to partly open the windows for ventilation, so you have to open it fully and so everyone can see you from the street and even grab something. Otherwise the smell is horrible (see p. #2) and there is no way to ventilate the ap;
4) There is no air conditionning, so sum up with p. #2 & #3 and imagine the situation;
5) There is a crazy grany leaving just on the left and up, empting out some kind of liquid on the street (seems like her peeing, but not 100% sure), which also smelt a lot;
6) It's very noizy at night until 2a.m. because of the parties taking place just nearby and dozen of crazy/drunk people passing throught the street and making loud noize and shouting different things;
7) Once a drunk teen from another on-fun group tried to get inside of the ap by the window and I had to hardly push him back by my foot; luckilly my wife was not alone at this time and was taking the bath behind the door;
8) The shower had a broken switcher so it was a mess to take bath; the owner haven't found a master after 2 weeks of our request;
9) No even shampoo/soap
10) The bed's size is approx. 120x175cm, so if you are heigher than 170cm - your foots will get outside. Also if you are not slim as we are - you'll have to sleep only straight. The small size was not mentionned in description.
11) A very small kitchen suitable for only a 1-2-times' breakfast cooking, not more;
12) There is no washing mashine; our request for the clothes dryer was confusing for the owner at first, but luckily provided in several days;
13) Several towels provided were in a bad condition. You expect at least not a n-years-old towel for this price;
14) The windows has opaque stickers so there is no way for the daily light to come in until you fully open the windows;
To sum up: this ap should be used as a last available option if you need to have a 1-night stay, or if you came in Porto for parties and spend in the ap approx. 5h per day to sleep only.
Otherwise it was the horriblest ap we ever booked. The place making you feel obligatory to spend the less time possible inside. Unfortunately, we came from Ukraine hiding from the war and we had to live and work here, so we were counting each day before leaving this smelling cave.
As a cherry on the pie you get the price above avarage for this stay.
