I have been in an apartment near metro station Avenida with 4 friends.
The apartment is cozy and clean and it works for 5 if someone is ready to sleep on the big couch.
Check-in and check-out are very convenient and we've been really happy about how responsive our Host Antonio was. For example he brought us some extra blankets to the apartment.
I highly recommend this accomodation and Antonio as the host!
