We stayed for a month in Alexey's appartment as a family of 2+2. I chose the location despite the mixed reviews and I'm happy having made that decision. Overall the stay was a good experience.
The host has several people working for him and usually you meet them on regular basis, not the owner. They set up a Whatsapp group for easier communication, so having this app is essential. I've asked to fix the TV antenna as it was not working in two of the three rooms and it was done promptly and without fuss.
The employees have limited English skills, so there is a bit of a challenge if you don't speak Spanish or Russian, although it's manageable.
The description is correct, although one could mention a few additional facts to make it complete. The appt is located on the 4th floor with stairs only, so there is quite a climb. The description doesn't mention that, but there is a small luggage lift which you can use to deliver your suitcases/groceries straight to the appartment without the need to carry them on the stairs. It's also not clearly marked that there is access to the rooftop terrace, which is shared between all the occupants of the building. If you live on the 4th floor, it's a short climb from there. There are some sunbeds on the roof and you can also hang your laundry for drying. There are TVs in each of the three rooms: a larger one in the living room/kitchen, plus two small ones in the bedrooms.
As mentioned by the owner, there is some noise from the streets in the neighbourhood up until approx. midnight due to several bars in vincinity, street cleaning, garbage collection, etc.
There was no problem with the utilities bill prepayment and reimbursion of the reserve, in the end the calculated cost was much lower than I expected.
Otherwise everything worked as expected and we had a good stay.
