I was staying in the apartment for 5 weeks in January 2020. I think Enriques place is well described - I'm adding my experiences:
- you are not in the centre. Colonia Doctores is not the central district, so do not expect to be polished like touristic areas. It is more or less area with technical or industrial shops. It is close to the old centre ( a bit of walk and two metro stations distance) and it is close to touristic areas like Roma. It is more being a local experience - which I like.
- the neighbourhood looks a bit shady, but I felt completely safe all of the time (!), even though I came home some times late in the nights with a local taxi. There is friendly (Spanish speaking) doorman in the building, which increases security feeling, and I also get friendly with some other locals around. But you know your selfs the best - if you are scared easily than you may not feel the same.
- there is extremely interesting market Mercado Hidalgo a block away. The local market where you can buy everything you wish to (go there!). Still, if you want some delicate goods you will need to go to western stile supermarket like Liverpool Parque Delta, which is 15min walking distance or euro and a half with a taxi (2 dollars).
- if you like to cook, as I do, then that is the place for you. The apartment has a good kitchen - you will find all the equipment you need - including mixer, and microwave, oven,..
- many people mention the park in front of the house, but I do not think the park has been fairly described. The Garden of the graphical arts (Jardin de las artes graficas) is really a beautiful park. In the mornings and in the evening when the sun is low it is most enjoyable to spend some times there. It is also free to use gym park equipment in the park.
- unfortunately, I did not meet Erique in person, but communication was delightful. The only thing I missing was more sun in the apartment - it gets cold in evenings, but I did some times climb to the rooftop, where you can not only catch some sun but also enjoy the remarkable view. Thanks for letting me have it.
