Me and my boyfriend went to posting for 3 days last weekend and we couldn't have picked a better place store stay!!!we lost our flight and ended up coming in Friday at 23.30 instead than at 18.00 and one of the hosts, Joao, rescheduled our taxi for us and waited for us in the apartment to give us the keys and so e much needed and vice!on the Saturday we wanted to take a tour on the Douro River and the guys helped us book it and met us to give us the tickets, honestly such a brilliant service!!Check pur is very easy, before 12 on the arranged day one just leaves the keys on the table and leaves, very handy!I would definitely recommend ORM and the crystal apartment to anyone visiting Porto as they are great, the apartment is wonderful (such a nice terrace too!!!) And the location is very convenient.
