This is an absolutely amazing place! Everything looks exactly like in the pictures. Sunrises and sunsets from the terrace are incredible. You got to eat a breakfast there! Host is super polite. He also speaks English very well (which is not super common in Barcelona I would say). He recommended me some cool places and events to visit and we had some interesting conversations in general.
Room is small but definitely not tiny. There is enough space for everything and there is even a desk and a chair for work in a room. Bedsheets and towels were clean, pillows comfy. It may be a bit cold in Barcelona at winter but there is an additional duvet you can use and it was enough for me to feel warm.
All instructions about getting to the apartment e.t.c. are super clear. There is a shelf in a kitchen for your food and also some space in the fridge.
Toilet and shower are clean. The water is heated using electrical hearer so after like 20 minutes in a shower water starts to get colder but it’s definitely enough time to shower and in an emergency situation you may just wait for ten minutes.
When I was booking this place, I was concerned about safety of the area where it’s located but it ended up being a super safe and quiet (!) district.
Overall I would definitely recommend this place! Definitely will visit again in the future.
