The GOOD news: large, spacious, clean apartment in an excellent location near La Rambla and Gothic Quarter.
The BAD news: the instructions on how to gain access to the apartment is complicated. No one meets you at the premises. Instead, Ola's Place asks you to download a phone app and complete pages of information before they provide an electronic key. The app is very buggy, and despite days of trying, three of us (each with our own phone) were unable to get the app working (re: spent hours of time watching three spinning dots and trying to interpret error messages). Even the link to the contract came up blank. This caused considerable delays gaining access to the apartment. After (finally) getting the electronic key, it was very finicky and buggy throughout our stay. It was normal meeting other groups at the front of the building struggling with their own electronic keys.
Not sure if staying anywhere that uses this app is worth the frustration.
