We had a great stay in Daniel's apartment - it was clean and was in a superb, very central location, literally right outside a metro station and multiple bus stops and a minute's walk from a supermarket, bakery and cafe. There is a nice park 5 minutes' walk away and it is really quick and easy to get to all the main attractions in Madrid from the apartment.
The apartment itself was the perfect size for 5 of us and the bathroom is huge. The basic essentials were provided; plenty of towels, shower gel and shampoo, toilet paper, washing up liquid and sponge. The beds are comfy and the shower was lovely. It was near the back of the building so was quiet despite us keeping all the windows open. It is on the sixth floor but there is a small lift which was great. The only downside was the lack of an oven in the kitchen but we got by with the stove.
Daniel was very informative and sent instructions very early on so we knew exactly what we were doing. Overall an excellent stay and I would definitely recommend one of Daniel's Airbnbs!
