The appartment of Alexey is perfectly situated near the Sagrada Familia, Passeig de Gràcia and multiple very nice restaurants.
The appartment itself was very clean and we were welcomed by Esperanza who gave us all the explanations we needed to find our way. She also had some tips about restaurants in the neighbourhood. The appartment has three bedrooms, but two of them are a bit smaller. So I wouldn't stay there with six persons, but for four persons (we were with a company of one couple and two singles) it had the perfect size. The bathrooms were complete, but small. But for a holiday you don't need more!
When I'm going to Barcelona, I would stay there again!
