The building and the apartment themselves are very modern and extremely well-kept. Check in was super easy, the internet was fast enough to work from the apartment. The apartment is a bit further away from the centre, but any part of the city can be accessed through the 2 metro lines very close to the apartment (as well as night buses that run regularly).
Pedro was a good host, very friendly. Sometimes it took him a bit to reply (to one request we got no reply at all during the stay). Nothing serious, though. He lives in the building, and he also told us to just knock on his door if we need anything. We can recommend the place for sure!
