From airport Sheremet'evo-2 (1) to the Moscow one can get by buses. They follows to the metro stations "Rechnoy vokzal" or "Planernaya".
The address of Lebedev Physical Institute is Leninskiy prospekt (Lenin's avenue) 53. To get to it one may from metro stations "Leninskiy prospekt" or "Oktyabr'skaya" by trolley-buses 4, 33, 62, 84 in direction from the Moscow centre to the stop "Univermag Moskva". From "Oktyabr'skaya" it is farther than one from "Leninsky Prospekt" but the trolley-bus stop is situated close to the metro exit unlike the "Leninsky Prospekt". After getting by the trolley-bus one should cross Leninskiy prospekt and walk in back direction (to the Moscow centre) 100-200 meters, where you will find Lebedev Physical Institute. Please do not confuse Lebedev Physical Institute with the neighbouring Lebedev Instiute of Mechanics and Calculating Mathematics (on this side of the street are many institutes situated one after the other). The session will be held (21 may) in the conference-hall of Lebedev Physical Institute. The entrance into institute will be free in that day.
The resthouse "Uzkoe" is situated on the South of Moscow (inside), but to get to it is not so suitable. The nearest metro stations are "Kon'kovo", "Teply Stan". But from these stations one needs, passing one-two stops by (trolley-)bus along Profsoyuznaya street, to walk long. It is more suitable to go farther by metro to the station "Yasenevo" (the exit from a head of a metro-train) and from it by trolley-bus N 85 go in direction of the Moscow centre a few stops (may be 4) to the stop "Sportbaza". By getting out trolley-bus, one should cross a road and walk about 5-10 minutes along alley (going through one arch) still it turns right, there the gate into resthouse "Uzkoe" will be. Nearly at the right there is a church. The resthouse itself is situated in a big park zone "Uzkoe".
Here you can see the picture scheme, explaining the way into resthouse. The possible routes are selected by black contours.
