The host is very nice and flexible with check-in and check-out times. The apartment was a little old (but I think that's normal for that quarter Barrio Gótico) but clean and it's very central.
We even had an umbrella for the beach (which is 15min by foot)!
We shared the apartment with 3 other guests (there are 4 rooms in total) and had a common bathroom and kitchen which were cleaned by the host (as far as I know).
Be aware though that smoking is allowed inside the apartment.
All in all, I would give 4 out of 5 stars.
