Staying at Martas and Noahs flat was the best thing that could happen to me during my 7 days stay in Barcelona. The flat is very clean and the room has a sufficient size, with a ventilator but no AC. The kitchen is fully equipped and the district around the house seems very safe. The hosts are always available via AirBnB if you need advice regarding your stay in Barcelona. Just know that it’ll take you 30 min to get to the city centre (walking and metro) and the flat is located higher than most of Gracia: so you need to walk 10 min uphill to get back home (good workout). In Gracia you can find a lot of nice Tapas Bars and shops run by locals, Park Güell is worth a visit as well. I would stay with them again!
