Although I didn't meet Egle personally, she was only an email away which she answered promptly.
The apartment is exactly as you see in the pictures. Modern, airy and luminous. The bed is comfortable, everything works in the kitchen and the shower has good pressure. There isn't a washing machine but this is not a problem as there are two laundry service shops, one next to the building, the other opposite it. They do a very good job and are extremely reasonably priced.
On arrival I met Oscar, the building caretaker, who handed over the keys. His wife cleaned the apartment once a week and provided fresh bed linen and clean towels. They are both delightful to deal with.
The neighbourhood is great, with many shops and reasonably priced restaurants within walking distance.
Another great feature is transportation; there are many buses that will take you to almost anywhere in the city and the subte Linea E (underground), is only 3 blocks away. You can be downtown in about 20'.
In short, this is a great little apartment in a lovely neighbourhood and I highly recommend it. Would I consider coming back to it on my next visit to BsAs? Yeah!
