Me and my husband stayed at Segundo's lovely accommodation in the end of September for 8 nights.
The room is exactly like the photos and it was pristine clean.
It is very functionally arranged with a large double bed ( I did not measure but maybe 150 cm wide) we are both quite tall and we were very comfortable. We had some of the in-built cupboards for our use which was more than enough for storage of our belongings.
Big windows in the kitchenette which overlooked some private courtyards and provided natural light and fresh air. After the reviews I have read of many similar accommodations in Barcelona, this was a very positive feature of the room. As the windows were not facing the main street, it was very quiet at night and we had a great sleep after a day of exploring the city. Also you could dim the room by electric shutters which was very convenient.
The bathroom is very functional with a standing shower cabinet and hot water with excellent pressure, also shampoo, conditioner and hand soap were provided.
There is a ceiling fan which we rarely used as the weather was nice, even a little chilly in the evening.
The kitchenette was very well equipped with an electric stove top, minifridge. kettle, pot, pan cutlery, plates, glasses, dish soap, sponge , broom and such for cleaning, moreover olive oil, vinegar and some spices.
The room, which is more like a small studio, is inside a flat on the 4th floor where the stairs are a little steep and narrow, but we are in our late fifties and could manage the stairs even twice a day which was a good exercise. The area is quiet and not so touristic which is a plus, the flat is 5 min walk from line 7 (FGC) metro station El Putxet from which Catalunya Square is about 12 min by metro. There are many restaurants around and supermarkets, one right across the street.
Communication with Segundo was excellent, he responded almost immediately and was available for questions and help, provided extra pillows, covers and mugs. He is a very courteous person, he and his girlfriend were a tremendous help. We didn't even notice that they lived in the same apartment, that's how quiet and respectful they were.
We enjoyed our stay very much and the next time we come to Barcelona we will surely stay at Segundo's place.
