I have some mixed feelings about this property, which I'll try to break down in detail:

Pros
1. Very central location within walking distance to many sights and attractions.
2. Two nearby supermarkets at a distance of 50-100 meters from the building entrance.
3. Very hospitable host (both him and his friend who handed over the keys upon check in), who even called a taxi for us at my request prior to checking out.
4. Comfortable bed with enough space for two adults.

Cons
1. Very old and tired kitchen with visibly marked flaws, which inevitably needs renovation; i.e. decaying or dislocated cupboard doors, yellowish and withered sealing by the sink etc. Miniature kitchen table plus 2 very basic chairs with very little space to sit at breakfast. In addition, the washing machine by the kitchen table (works just fine), had a little leak. Moreover, the kitchen worktop hasn't been cleaned thoroughly, thus we had to clean it and some other kitchen instruments the first morning.

2. The bedroom serves more for storage of the host's belongings without leaving much free space for guests, i.e. of two locked cupboards only a single door was available, and even then it had personal belongings inside. Some additional artifacts could have been removed to allow better access.

3. Living room floor not clean enough, which meant having to wash my feet before getting into bed or wearing shoes.

4. Shower-has very little space to move, i.e. the bathtub door slides in an out so that it actually hovers a few centimeters above the toilet. In addition, water splashes to the floor as the bathtub door doesn't provide sufficient protection. Aside from that the towels provided were far too small-I'd expect much bigger ones for use by adult guests.

5. The entire apartment is full of power extension blocks in every corner-not what you'd expect to find in a holiday apartment.

8. Lighting-some lightbulbs in the hallway were either burnt or missing. In the bedroom, for instance, the overhead chandelier wasn't working at all.

My overall impression, to sum up the enjoyable three-night stay in Madrid, is that this apartments does not meet modern standards, while the host, on the other hand, was very kind and welcoming. I am therefore not likely to rebook this apartment in the future.
