Hugo is an amazing host! He was very responsive to messages and arranged airport transfers for my friend and I and was very helpful in letting us get to the flat and dropping our bags. Also, if you can't get into the flat to drop bags, Santa Apolonia station is a short walk away and there is a luggage locker there that is easy and cheap to use.
The flat is in a great location-easy to get to and from everything and was perfect for our stay there. There are a couple sets of stairs that you will need to go up, so be sure you can carry your bags!
Would certainly stay here again!
