This is a tough one to review. I'll start with the positives. Marta & Paul have a beautiful apartment, there is no doubt about it. It was large & roomy & we had plenty of room for storage, which we greatly appreciated. We loved large window in the bedroom & the bed was very comfortable. Everything was as described & Marta & Paul were easy to communicate with.
However, we did not appreciate the late check-in/early check-out policies. If you are planning on staying here PLEASE watch out for these. I take fault as I should have reviewed these better in advance. Our flight was delayed so we arrived at the apartment 10 minutes past 9. My mom & I had to wait at least 15 minutes for our host to let us into the apartment. We were then charged 30 euros for our 'late' check-in, even though we had to wait to get into the apartment. It's a very weird concept to be charged for having LESS time in the apartment. If you leave early in the morning you must be very careful, they will get you for 50 euros!!! For the price we payed to stay here it was disappointing that no extra amenities were included at all. No shampoo, conditioner, not even coffee! It's clear that this apartment is ran like a very strict business & lacked the friendly, helpful, accommodating hospitality that you often find when staying at an airbnb. (Maybe I've been spoiled in the past with too many excellent experiences?)
Overall it is a nice apartment. But due to their check-in/check-out policies & what we got for what we payed for... I will not stay here again when I return to Barcelona.
