We had a great stay at Vicky's. Location wise it is central to all parts of the city and Vicky was kind enough to guide us through how public transport works in Barcelona. The house was spick and span. The only drawback would be that the unattached washroom is extremely tiny for an adult. The washroom looks bigger in photos . Also, the AC wasn't working to its full capacity. Otherwise the entire experience has been smooth from check in to check out.
P.S : There is a cafe opposite to Vicky's called La Rocha. The brunch there was so good that we ended up eating there for 3 days straight :)
