We arrived very late (1am) and Ruben was still waiting for us although himself is not staying there. Having know we need coffee and will leave very early for our trip, he went out to buy coffee and milk for us! When we wondering where to leave our bag on the last day after we checked out, he said we can leave our bag in the flat for free. A small downside is the single-bed room which faces to the street were quite noisy, can hear people singing and shouting after their party. But the other double-bedroom is very quite. Overall, it is a very pleasant stay, and Ruben was very friendly and very helpful! Thank you very much Ruben!
