My stay in Numa/Roca's apartment was perfect - from the first contact during booking till the farewell and option to keep your baggage in lockers after the check-out, before departing Barcelona.
The communication was great - easy, in friendly tone, with clear instructions and prompt answers. "Digital" check-in went smoothly. No keys, no cards, you use only (one/same) pin for everything. The apartment was perfectly clean, looking absolutely the same as in photos, with spacious bathroom, very comfy bed, good wi-fi, free snacks and range of drinks (coffee, teas, juice...). I didn't use common spaces (lounge, kitchen...), but everything looks great, clean and tidy, pleasant and enjoyable. Retro decor is amazing. Location is very good - 50 m from metro stop, 7-8 min walk from train station with airport connection.
I am particularly grateful for earlier check-in, that may be permitted upon the availability. Luggage lockers are super-convenient advantage, providing few more hours of relaxed wandering in vivid Barcelona. It's not common option in staff-less properties and that is one more item making Numa/Roca exceptional.
Although the price was a bit high, it was among most affordable for what I was looking for and I would say the value is worth of money. It would be my pleasure to stay there again and to recommend it to other travellers.
Go on Numa/Roca, you're doing it very well!
