We really enjoy our stay at 7th Heaven place. Its so easy to find it. The location is great, close to underground station 5min walk and its walkable to the city center aswell.
The host (Verena) was really nice and very communicative about everything that we need. She gave us a bottle of champagne (cava) as well.
We really like the unit, its very cozy and basically it has everything that you need (kitchen, kettle, bath tub, tv, dvd, dish washer, washing machine, nespresso, coffee, tea, etc)
