Huge disappointment -are two reasons for this.
Firstly the ability to manage urgent situations: We had only one key for 4 days and the accommodator could not fix this - first we were told it would take 5 minutes to give a new card - it took four days to get this fixed. The communication on this issues (that they were not able to provide the new key) was not transparent at all. On the weekend I was standing behind the door and tried to call to 24/7 number of Stay U-Nique - it went to answering maschine and no one ever called me back. Imagine standing behind the door in a city you have no contact to call. When we told this to the representative who showed up after four! days - he laughed at us. Funny?
Secondly - the apartment and the roof top terrace does look very different today - perhaps they looked like in pics some years ago when they were freshly renovated. Not any more. Everything is slightly wornout - floors, wall papers etc. There are very few electric outlet in the apartment as well. In kitchen one outlet - for toaster, water heater, micro vawe and coffee machine. In addition, the apartment is not sound proof. You could hear everything from next door apartment and from the corridor - Lucky us, we had young guys next door who had come to party to Barcelona. In our apartment partying was not allowed ("no partying; > 30 yrs old") but in the next door this was ok? Not to mention that the windows which are nice and big in the apartment , but they were so disgustingly dirty and the Hell´s Angels club house is cross the street.
