I stayed for 3,5 nights at Alex's house. It was quite a good experience, especially considering the price! And after many trials I endured in Malaga and Madrid with accomodation 🤪 At least, all that's written here tells a true story. Most importantly, veeeery comfy pillows and adequate mattress!!! I had to say that 😂 Alex is very busy but open for conversation and professional in his approach to his guests. The flat is located 3 min away from the metro Vallcarca, it's a bit inconveniently placed away from the airport but I managed to take 2 buses to the centre and then to the airport at 3:30 AM anyway. I adored the old house vibe. It was a bit chilly but on the third night the central heating turned on so it became very warm. What can trouble you is really thin walls, people do gather at the small square at night. Yet, earplugs helped perfectly. Only one night there was a real party with the loud music outside. The walks are thin between the rooms too so it depends on your neighbors schedule if it's gonna be quiet at night as well. Alex asks everyone to keep quiet after 22:00 but if course nobody takes it literally. I was lucky to share my floor (3 rooms) with good neighbors. It was very nice actually to meet a professor from Chili in the kitchen. We had a couple of good evening conversations with the wine 🍷 There's hot water in the tubs and a washing machine if you need it. There was a terrace but it was too chill for me at night so I didn't go out there. Definitely recommend if you want to save up a bit as Barcelona is very expensive in general.
