We (5 friends) spent Easter in Vaninas Appartement in Barcelona and had a great time. We didn't get to meet Vanina but she always helped out and answered quickly whenever we messaged her during our stay. The apartment is equipped very well and has everything you need. There also was enough space for all of us, even though the apartment appears bigger on the pictures than it actually is. We did have some problems with the hot water in the shower which didn't function very regularly. Possibly due to the five of us showering after each other. We also noticed that not everything was completely clean.
We liked the neighbour hood since it was not touristy at all and close to a lot of cool bars and restaurants mainly visited by locals. The apartment is super close to the subway stop and in walking distance to the ramblas. If you are looking for a place away from the masses, this place is a good choice.
