The house is located on a residential and quiet neighborhood on the side of a mountain. It has markets and some bars nearby and it is 2 minutes walking from the nearest metro station. Pretty well communicated from downtown and particularly near Vall d'Hebron hospital (15 minutes walking or just one train station). Also there are many green zones nearby.
The house itself is located after a few steep steps. It is a really charming house, 3 floors. It is tastefully decorated with many interesting things kept from a life well lived. It is spotlessly clean.
You can make use of most of the house, except another room for other guests and the room of the owners themselves.
The room I stayed in was on the top floor, it was a small, funcional and cozy room; with a very comfortable bed and a nice private balcony. Across the floor there are the shared bathroom and another balcony with some appliances and plants, very unique places I was provided plenty blankets and two clean towels. The WiFi was fast and reliable.
And I've left the best for last, and that were the owners. Adrian and Val are one of the nicest, most interesting flexible and adaptable people I've ever met. You are not just a guest, you are a friend. I was a bit afraid because it was the first time I shared a house with the hosts and I doubt It could have been better. The three dogs were are also charming and cute, very well behaved yet affectionate if you wanted (they sleep at the owners room).
The only thing I regret is to have stayed just two nights.
