#1 positive: PERFECT location. You are in the middle of everything. All major sights/attractions are within easy walking distance. There are TWO Metro stations (Sol and Callao) within a block or less. One side of Sol station has access to the Cercanias commuter rail line, which gives access to even more of Madrid and its suburbs. EVERYTHING you need (shopping, groceries, pharmacies, restaurants, cafes, tapas bars, churrerias, even cinemas, etc.) is on the street, or within a few blocks. And even more on Gran Via. This reason alone is well worth booking the apartment. Other positives: 1. Very pleasant dealing with host Irene via Airbnb messaging. Her colleague helped with check-in and gave very helpful tips on things to see/do in Madrid. 2. Spacious apartment. Clean. Modern. Tastefully furnished. Has all the kitchen stuff you need to make meals. 3. Private and generally quiet. It's on the quiet side of the building, away from the street. You will not hear street noise. 4. Secure. Front entrance + landing entrance + apartment entrance, that's three different keys. 5. Big comfortable bed for two. Bathtub in bedroom. More sleeping space on the convertible sofa in the living room. Two bathrooms. 6. Parking is included, although it is in another building very close by. (More on this below). ---- Unfortunately there are some negatives (listed in order of severity): 1. Shower is a mess. Even with a shower curtain/shade, there is no barrier on the shower floor to stop water from flowing into the lower bathroom floor. Every day after you shower there's always a mess of water in the bathroom and the only solution is to mop it with the shower mat. 2. Water temperature in the shower and all faucets in the apartment is very erratic and inconsistent, sometimes extremely hot, sometimes extremely cold. 3. Bread toaster in the kitchen is dangerous and a fire hazard. You put slices of bread almost directly on the heating elements, which have no cover or protector. There is no automatic off-switch and temperature regulator so it's very easy to burn your bread or anything that sits near the toaster. 4. The wifi is very slow everywhere in the apartment. 5. Both bathrooms have an odor problem, presumably because the sinks don't have a trap (a U-, S-, or J-shaped pipe under the sink that stops bad odors coming back from the sewer). --- Other negatives: 1. Parking spot is in the basement of another building that can be accessed only with a very narrow car elevator. It's very easy to scratch your car, damage your mirrors, or dent your doors if you're not extremely careful. The underground level itself does not have much room to maneuver either, though it is possible. An economy or compact rental car should be manageable, but you must be extremely careful getting in and out of the car elevator and the garage. 2. Apartment elevator is very small, barely fits two people with luggage. It does not stop on...
